GATE.

SPECIFICATIONAforming part of Letters Patent No. 270,957, dated January 23, 1883,

Application tiled May 13, 1832. (No model.) l

To all whom it may concern:

Be it known that I, ISRAEL L. LANDIS, of Lancaster, in the county of Lancaster, and in' the State of Pennsylvania, have invented certain new and useful Improvements in Gates; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference marked thereon making a part of this specification.

This invention relates to certain improvements in gates; and it has forits object to provide for elevating the gate obliquely and also vertically to raise it above snow or for other purposes, and to provide an improved means for locking the gate, as more fully hereinafter specified. These objects I attain bythe means illustrated in the accompanying drawings, in which- Figure 1 represents a side elevation of my invention,showing the gate obliquely elevated in dotted lines. Fig. 2 represents a detached view, showing the mechanism forelevating the gate vertically. Fig. 3 represents a horizontal section of the gate-hatten, showing the means of attachngthe hinge-leaf thereto. Fig. 4 indicates a transverse vertical section of the gate, and Fig. 5 represents a transverse vertical section ofthe latch-bolt and device for securing it to the gate.

The letter A'represents agate-post of ordinary construction, which is provided with pintles B, upon which the hinge-leaves C swing. The said leaves are constructed of metal, and are provided each with a straight arm, D, and a bent arm, E, the extremities o't' which sit in longitudinal grooves F on opposite sides of the batten G. The hatten, near its upper end, is provided with a rack, H, and the upperhinge-wing with a-pinion, I, mounted. on a crank-shaft, R, journaled in slots L in the said upper wing, whereby the ba-tten may be elevated or depressed.

The letter lll indicates adetent journaled in bearings N in the upper wing, and provided with a crank, P, by means of which it may be thrown into gear with the rack t hold the hatten in any desired position.

The letters R R indicate the gatebattens,

- and S the gate-rails, which are pivoted beoted to the gate-rails near the center of the I gate; and U, two oblique sliding bars, which are pivoted respectively to the upper and lower rails near their ends, as shown. The said bars rest against and are adapted to slide upon each other, and pass between a cleat or clamp, V, pivoted to two of the gate-rails and to the batten T, one of the pivot-bolts being provided with a clamping device, W, by means of which it can be tightened against the bars and hold the said bars and the gate-rails in any desired position. p

The letter Y indicates a pin secured to one of the rails, and bearing against the upper sliding bar to keep it in place.

The letter Al indicates the latch-bar, which is provided with an inverted-U-shaped spring, which embraces one of the gate-bars and bears against it with pressure sufficient to hold the bar to the rail. The said spring passes loosely through the latch-bar in such manner as to permit the bar to be moved back and forth, so that it may be projected into a suitable socket in the gate-post at the free end of the gate or withdrawn therefrom, as occasion may require.

The lower hinge-leat'is provided with afriction-roller, B', in order to permit the hatten to ride freely therein, and the post A is provided with a pin, C', which oversits the lower pntle and holds the gate in place.

The operation of my invention is as follows:

To elevate the gate vertically, the crank-shaft K is rotated so as to raise the hatten G by means of the rack and pinion. When sufficiently elevated, the detent is caused to engage the rack, so as to hold the gate at the required elevation. When it is desired to elevate the gate obliquely, the sliding bars are loosened by loosening the cleat or clamp, and the gate is elevated at its forward end until it has assumed the desired angle, when the bars are clamped, holding it in position..

It is evident that my invention may be ap plied to old as well as new gates by removing the old hinges and substituting the improved hinges and hatten.

Having thus fully described my invention,

IOO

what I claim, and desire to secure by Letters Patent, is-

l. The combination, with the hatten provided with a rack, of thev hinge-leaves secured thereto in longitudinal recesses, and the pinion and detent, whereby the gate may be elevated vertically and held, substantially as specified.

2. In combination With the battens having pivoted between them the rails of the gate, the oblique sliding bars attached to opposite corners and crossing the gate diagonally, and the clamping devices, adapted to operate sul)- stantially as specified.

3. In combination with the gate, the gate- 15 latch provided with a loosely-attached spring adapted to embrace one of the gate-rails and swing upon the saine as upon a pivot, to hold the latch and permit it to be shifted7 substantially as specitied.

In testimonyT whereof I aix my signature, in presence of two witnesses, this 25th day ot' April, 1852. g isRAEL L. LANDIs. Witnesses: I f
